11216         (complete_array_type): We need to work with the canonical main

11225         own canonical type.
11226         (build_type_attribute_qual_variant): When building an attribute
11227         variant, its canonical type is the non-attribute variant. However,

11240         (build_index_type): When we can't hash an index type (e.g.,
11241         because its maximum value is negative), the index type requires
11242         structural equality tests.
11243         (build_array_type): Build the canonical form of an array type.
11244         (build_function_type): Function types require structural equality,
